BRACKET-PIECE FOR SCREEN-FRAMES.

SPECIFICATION forming part of Letters Patent No. 230,438, dated July 27,1 880, I

7 Application filed December 27, 1879.

To all whom it may concern:

Be it known that I, EDWARD N. PORTER, of Morrisville, in the county ofLamoille and State of Vermont, have invented a certain new and ImprovedBracket or Corner Piece for Screen-Frames, 850.; and I do hereby declarethe following to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a front view of one of the bracketsapplied to a frame. Fig. 2 is a perspective view of the same with theframe represented in dotted lines, and Fig. 3 is a perspective view of amodification.

Similar letters of reference in the several figures denote the sameparts.

This invention has for its object to provide improved corner-bracketsfor binding together the parts of light frames, such as are used forwindow and door screens, whereby the said frames will be materiallystrengthened and the jointing of the parts by tenon and mortise orotherwise rendered unnecessary.

To this end the invention consists of a bracket or corner piece having aface-plate adapted to rest against the outside of the frame, and aninwardly-projecting angular flange adapted to fit the inner corner ofthe frame, and provided with. lateral lugs or spurs for enteringcorresponding recesses or slots in the parts of the frame, substantiallyas I will.

now proceed to describe.

The entire bracket or corner piece is preferably made of metal and castin one piece. Its face-plate A is formed in an ornamental design, and isprovided with holes or perforations a a for the passage of screws bywhich to secure it to the frame.

'On the back side of the plate A an angular flange, B, is f rmed, whichprojects inwardly and fits the corner of the frame formed by the comingtogether ofthe parts 0 G.

Lugs or spurs I) I) project laterally from the outer side of the flangeB and enter corresponding slots or recesses in the parts 0 G, as shownin Fi 2. The parts 0 G are preferably brought together without jointing,as shown, and the corner is then applied and secured firmly by means ofscrews passed through the holes or perforations a a in the face-platebefore alluded to, and other screws applied through similar holes inperforations d cl in the angular flange B.

By the use of my improved brackets or corher-pieces the frames can bemade very light and cheap and can be put together quickly and firmlyWithout requiring a skilled workman, as where the parts are jointed.

I am aware that a metal corner-piece or bracket consisting of aface-plate and an inwardly-projecting angular flange adapted to fit theinner corner of the frame has heretofore been invented, as will appearfrom the patent granted to J. Brizee, dated July 16, 1878, and numbered205,995, and I do not therefore claim herein such construction,broadly.Q

I claim as my invention- The brackets or corner-pieces herein described,having the faceplate A, the in wardl'yprojecting angular flange B,provided with the lugs or spurs b b, and adapted to be secured to aframe in the manner substantially as set forth.
